Application filed August 2, 1913. Serial No. 782,574.

My invention relates. to a novel construc- 1 tion for anchoringor supporting door posts which are subjected to severe strainsand has particular reference to freight car construction.

The object of the invention is to provide improved means for supporting the door posts of box cars and the like, which are now frequently torn from their fastenings by heavy pressures from within produced by loads such as grains. The usual method of fastening these posts. to the outside sills of the car is to form a tenon in the post and a mortise in the sill with the result that the tenon is often broken off or the sill is split.

Another object of the invention is to pro 'vide means of repairing the support of posts havingtheir tenons broken in the manner indicated and making it possible to utilize the broken door post and support it even better than it was supported before being broken.

WVith these general objects in view my invention consists in the novel construction for this portion of a box car, and in the combination and arrangement of parts. all as hereinafter described in detail, illustrated in the accompanying draWingand incorporated in the appended claims.

In the drawing-Figure .1 is a perspective View of a section of a boxcar. Fig. 2 is an enlarged irregular section taken substantially on line 2-2 of Fig. 1. Fig. 3 is a section taken substantially on line 3-3 of Fig. 1. Fig. 4 is a perspective View of the socket or casting in which the end of the door post is seated. Fig. 5is a perspective view representinga section of car floor and door post, showing the usual joint and the manner in whichthis joint is often broken.

Referring in detail to the several views, 2 represents the body of a section of box car; 3 is the flooring laid on sills 4, 5, 6, 7, 8, and 9, and 10 and 11 are door openings each of which is partly framed by a pair of door-posts 12 and 13, the support of which is the subject of the. present inven tion. The usual method ofsupportingithe door posts on the bottom of the car is shown in Fig. 5, where 1 1 represents a mor-.

tise cut in the sill 1 and 15 a tenon formed on the endof the post 12. In Fig. 5 both these parts of the joint are shown broken. The construction shown inl the remaining views is adapted to use the post 12 after itstenon has been broken off,..or.to use. the sill 1. as a support for the door post after it has been splintered by the tenon, the brokenotl', or splintered, portion being rep resented as 4.

In lieu of the mortise 1 1 I provide a casting, or otherwise suitably formed post support 16 in which is a recess 17 adapted to. receive the end of the post unreduced in size, as by the tenon 15. On the casting or support 16 are lugs or extensions 18 and 19, each of wh1ch 1s pierced by a bore 20.

through which passes a bolt 21. Thus two bolts are used for the support of each casting. These bolts or rods extend through the second sill 5 at the one side, or 8 at the opposite sides, which are usually termed the intermediate sills. The portion 17 is termed the socket portion and may extend above the surface of the floor, but the lugs 18 and 19 are designed to have their upper surfaces flush with the upper surface of the floor while the front 22 of the socket portion is flush with the sidingof the car, indicated as 23. The front 22of the socket portion is therefore offset from the lugs to form recesses 24 and 25 of a depth equal to the thickness of the siding. Theonly casting surfaces exposed are the top surfaces of the lugs and the front face 22 of the socket portion together with the narrow rim of the socket portion. The bolts or rods which fasten the casting to the intermediate sill are covered by the flooring and this is sufficient to hold the casting in place against vertical movement. As the flooring is laid transversely of the length of the car only the two flooring boards over the bolts need be removed in order to make repairs.

The door posts are exposed to consider- Having thus described my invention, 15 claim as new and desire to secure by Letters Patent I 1. The combination with a box car and the door posts therefor, of the floor and floor supporting sills, socket members receiving the lower ends of said door posts,

said socket members resting on the outer sills, and bolts securing said socket mem bers to the intermediatesills, said bolts between said outer and intermediate sills be ing covered by said floor.

2. The combination with the floor, floorsills and siding of a car, of the door-post, a socket-member which receives the lower end of said door post and supports same against outward movement, lugs on said Copies of this patent may be obtained for set my hand in the presence of two sub-'- soribing witnesses.
